Embodiments of the present disclosure are discussed in detail below. It should be appreciated, however, that the present disclosure provides many applicable concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative and do not limit the scope of the disclosure.

FIG. 1 illustrates a cross-sectional view of a semiconductor device package 1 in accordance with some embodiments of the present disclosure. The semiconductor device package 1 includes electronic components 10 and 11, substrates 12 and 14, an interposer 13, and encapsulating layers 15 and 16.

Each of the substrates 12 and 14 may be, for example, a printed circuit board, such as a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated glass-fiber-based copper foil laminate. Each of the substrates 12 and 14 may be, or may include, an interconnection structure, such as a redistribution layer (RDL) or a grounding element.

The substrate 12 has a surface 121 and a surface 122 opposite to the surface 121. The substrate 12 may include one or more conductive pads 12 p in proximity to, adjacent to, or embedded in and exposed at the surface 121 of the substrate 12. The substrate 12 may include a solder resist (not shown) on the surface 12 of the substrate 12 to fully expose or to expose at least a portion of the conductive pads 12 p for electrical connections. Electrical contact 12 b 1 (e.g. a solder ball) is disposed on the conductive pads 12 p and can provide electrical connections between the semiconductor package device 1 and external components (e.g. external circuits or circuit boards). In some embodiments, the electrical contact 12 b 1 includes a controlled collapse chip connection (C4) bump, a ball grid array (BGA) or a land grid array (LGA). Opposite to the surface 121 of the substrate 12, an electrical contact 12 b 2 is provided on the surface 122 of the substrate 12 through a solder paste to provide electrical connections to external components.

The electronic component 10 is disposed on the surface 122 of the substrate 12. The electronic component 10 may be a chip, a die including a semiconductor substrate, a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), or the likes. The electronic component 10 may include one or more integrated circuit devices (such as active devices and/or passive devices) and one or more overlying interconnection structures therein. The electronic component 10 may have high input/output (I/O) connections to meet high bandwidth specifications. As shown in FIG. 1, the electronic component 10 has an electrical contact 10 b electrically connected to the substrate 12 and an underfill 10 u surrounding the electrical contact 10 b. In some embodiments, the electrical contact 10 b may include a micro bump, a C4 bump, a BGA or a LGA. In some embodiments, the underfill 10 u may include an epoxy resin, a molding compound (e.g., an epoxy molding compound or other molding compound), a polyimide (PI), a phenolic compound or material, a material including a silicone dispersed therein, or a combination thereof.

The encapsulating layer 15 is disposed on the surface 122 of the substrate 12 to cover and encapsulate the electronic component 10. In some embodiments, the encapsulating layer 15 may include, for example, one or more organic materials (e.g., a molding compound, bismaleimide triazine (BT), a PI, a polybenzoxazole (PBO), a solder resist, an Ajinomoto build-up film (ABF), a polypropylene (PP), an epoxy-based material, or a combination of two or more thereof), inorganic materials (e.g., silicon, a glass, a ceramic, a quartz, or a combination of two or more thereof), liquid-film material(s) or dry-film material(s), or a combination of two or more thereof.

Similar to the substrate 12, the substrate 14 has a surface 141 facing the surface 122 and a surface 142 opposite to the surface 141. The substrate 14 may include one or more conductive pads 14 p. Electrical contact 14 b is disposed on the conductive pads 14 p to provide electrical connections to external components.

The electronic component 11 is disposed on the surface 142 of the substrate 14 and electrically connected with the substrate 14 through a flip-chip technique, a wire bonding technique (e.g., through a wire 11 w), or other suitable technique. The electronic component 11 may be a chip, a die including a semiconductor substrate, a semiconductor memory (e.g., a dynamic random-access memory (DRAM)), or the likes.

The encapsulating layer 16 is disposed on the surface 142 of the substrate 14 to cover and encapsulate the electronic component 11. In some embodiments, the encapsulating layer 16 may include a material as noted above for the encapsulating layer 15.

The electronic component 10, encapsulated in the encapsulating layer 15 and disposed on the substrate 12, is electronically connected to the electronic component 11, encapsulated in the encapsulating layer 16 and disposed on the substrate 14, through the interposer 13 and an electrical contact 13 b provided thereon. The interposer 13 is disposed between the electronic component 10 and the substrate 14. The interposer 13 may include, for example, a printed circuit board, such as a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated glass-fiber-based copper foil laminate. The interposer 13 may be, or may include, an interconnection structure, such as a RDL or a grounding element.

A sum of a thickness of the interposer 13 and a gap between the surface 141 and the interposer 13 is equal to or greater than 200 micrometer (μm), 230 μm, 250 μm, or more. A sum of the thickness of the semiconductor device package 1 is equal to or greater than 1.0 μm, 1.03 μm, 1.06 μm, or more.

With the interposer 13 in the semiconductor device package 1, the memory device (such as the electronic component 11) can be electrically connected to the logic device (such as the electronic component 10) by vertically stacking to each other through package-on-package (PoP) technique. However, as technology advances, a semiconductor device package having a further reduced thickness is desired. In addition, as shown in the FIG. 1, the current from the electric component 10 to the electric component 11 flows through the electrical contact 10 b, the substrate 12, the electrical contact 12 b 2, the electrical contact 13 b, the substrate 13, the electrical contact 14 b, the substrate 14, and the wire 11 w. As technology advances, chips are provided with relatively more I/O connections in, for examples, High Bandwidth Package on Package (HBPoP). The length of the circuit loop in the semiconductor device package 1 of FIG. 1 is long and may adversely affect the performance thereof.

FIG. 2 illustrates a cross-sectional view of a semiconductor device package 2 in accordance with some embodiments of the present disclosure. The semiconductor device package 2 includes electronic components 20 and 21, substrates 22, and 23, and encapsulating layers 24 and 25.

The substrate 22 may have a material and/or a configuration as noted above for the substrates 12 and 14 in FIG. 1, and may have a conductive layer 22 r. As shown in FIG. 2, the substrate 22 has a surface 221, a surface 222 opposite to the surface 221, and a surface 223 (such as a lateral surface) connected between the surfaces 221 and 222. Electrical contacts 22 b 1 and 22 b 2 are disposed on the surfaces 221 and 222 of the substrate 22 to provide electrical connections to external components.

The electronic component 20 may have a material and/or a configuration as noted above for the electronic component 10 in FIG. 1. The electronic component 20 is disposed on the surface 222 of the substrate 22. The electronic component 20 has a surface 201 (such as an active surface) facing the substrate 22 and a surface 202 (such as a backside surface) opposite to the surface 201. The electronic component 20 includes an interconnection structure 20 r 1 (such as a RDL) on the surface 201. The electronic component 20 includes an interconnection structure 20 r 2 on the surface 202. The electronic component 20 includes a conductive via 20 t (such as a through silicon via (TSV)) therewithin and electrically connected the interconnection structure 20 r 1 to the interconnection structure 20 r 2. An electrical contact 20 b (surrounded by an underfill 20 u) is provided on the interconnection structure 20 r 1.

The interconnection structure 20 r 1 and the electrical contact 20 b provide the electrical connection between the electronic component 20 and the substrate 22. In some embodiments, the electronic component 20 is devoid of the interconnection structure 20 r 1 on the surface 201, and the electrical contact 20 b is provided on the surface 201 of the electronic component 20.

The interconnection structure 20 r 2 and the electrical contact 23 b (disposed on a surface 231 of the substrate 23) provide the electrical connection between the electronic component 20 and the substrate 23.

A buffer layer 26 is disposed between the interconnection structure 20 r 2 and the substrate 23. The buffer layer 26 may include an adhesive, a glue, or other suitable material, such as a material for die-attaching.

Still referring to FIG. 2, the substrate 23 may have a material and/or a configuration as noted above for the substrates 12 and 14 in FIG. 1, and may have a conductive layer 23 r. As shown in FIG. 2, the substrate 23 has a surface 231 facing the surface 202, a surface 232 opposite to the surface 231, and a surface 233 (such as a lateral surface) connected between the surfaces 231 and 232. The electrical contact 23 b is disposed on the surfaces 231 of the substrate 23 to provide the electrical connection to the electronic component 20 and the substrate 22.

The electronic component 21 may have a material and/or a configuration as noted above the electronic component 11 in FIG. 1. The electronic component 21 is disposed on the surface 232 of the substrate 23 and electrically connected with the substrate 23 through a flip-chip technique, a wire bonding technique (e.g., through a wire 21 w), other suitable techniques.

The encapsulating layer 25 may have a material and/or a configuration as noted above for the encapsulating layer 16 in FIG. 1. The encapsulating layer 25 is disposed on the surface 232 of the substrate 23 to cover and encapsulate the electronic component 21. As shown in FIG. 2, the encapsulating layer 25 has a surface 251 substantially coplanar with the surface 233 of the substrate 23. The surface 251 of the encapsulating layer 25 and the surface 233 of the substrate 23 are in contact with the encapsulating layer 24.

The encapsulating layer 24 may have the same material as encapsulating layer 25. In some embodiments, the encapsulating layer 24 and the encapsulating layer 25 may have different materials.

The encapsulating layer 24 is disposed on the surface 222 of the substrate 22 to cover and encapsulate the electronic component 20. The encapsulating layer 24 surrounds the electronic component 20, the substrate 23, and the encapsulating layer 25. The encapsulating layer 24 includes a surface 241 substantially coplanar with the surface 223 of the substrate 22. The surface 241 of the encapsulating layer 24 and the surface 223 of the substrate 22 are spaced apart from the surface 251 of the encapsulating layer 25 and the surface 233 of the substrate 23. The surface 241 of the encapsulating layer 24 and the surface 223 of the substrate 22 surround the surface 251 of the encapsulating layer 25 and the surface 233 of the substrate 23. The surface 251 of the encapsulating layer 25 and the surface 233 of the substrate 23 is recessed from the surface 241 of the encapsulating layer 24 and the surface 223 of the substrate 22. The surface 251 of the encapsulating layer 25 and the surface 233 of the substrate 23 is surrounded by the surface 241 of the encapsulating layer 24 and the surface 223 of the substrate 22.

The electrical contact 23 b provided on the surface 231 of the substrate 23 may be stacked on the electrical contact 22 b 2 over the surface 222 of the substrate 22. The electrical contact 23 b stacked on the electrical contact 22 b 2 is disposed next to the electronic component 20. In some embodiments, the electrical contact 23 b stacked on the electrical contact 22 b 2 may be replaced with a solder ball or a cupper (Cu) pillar.

The current from the electric component 20 may flow to the electric component 21 through the interconnection structure 20 r 1, the conductive via 20 t, the interconnection structure 20 r 2, the electrical contact 23 b, the conductive layer 23 r in the substrate 23, and the wire 21 w. The circuit loop in the semiconductor device package 2 of FIG. 2 is shorter than the circuit loop in the semiconductor device package 1 of FIG. 1, which helps to achieve a better performance thereof. The current from the electric component 20 may also flow to the electric component 21 through the electrical contact 20 b, the substrate 22, and the electrical contacts 22 b 2 and 23 b (which is a circuit loop similar to that in the semiconductor device package 1 of FIG. 1). By this way, the current from the electric component 20 can be distributed, for example, the current directly passing through the conductive via 20 t may be used for high-bandwidth transmission, and the current passing through the electrical contacts 22 b 2 and 23 b may be grounded.

In addition, since the current may flow from the interconnection structure 20 r 1 to the substrate 23 through the interconnection structure 20 r 2 and the electrical contact 23 b, an interposer may be omitted in the semiconductor device package 2, which helps to reduce the thickness of the semiconductor device package 2.

FIG. 3 illustrates a cross-sectional view of a semiconductor device package 2′ in accordance with some embodiments of the present disclosure. The semiconductor device package 2′ of FIG. 3 is similar to the semiconductor device package 2 of FIG. 2, and the differences therebetween is described below.

The encapsulating layer 25′ may have a material and/or a configuration as noted above for the encapsulating layer 25 in FIG. 2. The encapsulating layer 25′ is disposed on the surface 232 of the substrate 23. The encapsulating layer 25′ is disposed on a portion of the surface 222 of the substrate 22.

The encapsulating layer 24′ may have a material and/or a configuration as noted above for the encapsulating layer 24 in FIG. 2. The encapsulating layer 24′ has a surface 241 substantially coplanar with the surface 233 of the substrate 23. The surface 241 is in contact with the encapsulating layer 25′. The surface 241 is surrounded by the encapsulating layer 25′. The encapsulating layer 25′ has a surface 251 surrounding the surface 241 of the encapsulating layer 24′ and the surface 233 of the substrate 23.

In some embodiments, the formations for the encapsulating layer 24 and the encapsulating layer 25 may be conducted in the same operation. For examples, the encapsulating layer 24 and the encapsulating layer 25 may be formed at the same time.
